| | Mpep hydrochloride Usage And Synthesis |
| Description | Glutamate, the major excitatory neurotransmitter in the brain, acts on both ionotropic and metabotropic glutamate receptors. Excessive metabotropic glutamate receptor (mGluR) transmission has been linked to epilepsy, ischemia, pain, anxiety, and depression. Eight subtypes (1-8) and multiple splice variants of the mGluR have been identified and grouped based on their pharmacological properties. Group I mGluRs (subtypes 1 and 5) activate the phosphatidyl inositol pathway, while Group II (2 and 3) and Group III (4, 6, 7 and 8) inhibit adenylyl cyclase. MPEP is a potent, highly selective non-competitive antagonist at the mGlu5a receptor subtype (IC50 = 36 nM) while having no agonist or antagonist activities at the mGlu1b receptor at concentrations up to 30 μM. MPEP is centrally active following systemic administration in vivo, inducing anxiolytic-like effects in rodent models of anxiety and depression when administered at 1-30 mg/kg. MPEP has also been reported as a positive allosteric modulator of mGluR4 at μM concentrations. | | Uses | Glutamate, the major excitatory neurotransmitter in the brain, acts on both ionotropic and metabotropic glutamate receptors.

MPEP has also been reported as a positive allosteric modulator of mGluR4 at μM concentrations. | | Uses | MPEP is a potent and highly selective non-competitive mGlu5a receptor antagonist (1,2). It is also a positive allosteric modulator at mGlu4 receptors.MPEP exhibits anxiolytic and antidepressant properties that may be applicable for treating schizophrenia (3). | | Definition | ChEBI: A methylpyridine that coinsists of 2-methylp[yridine bearing an additional phenylethynyl group at position 6. Potent and highly selective non-competitive antagonist at the mGlu5 receptor subtype (IC50 = 36 nM) and
positive allosteric modulator at mGlu4 receptors. Centrally active following systemic administration in vivo. Reverses mechanical hyperalgesia in the inflamed rat hind paw. | | General Description | GRIN2B (glutamate ionotropic receptor NMDA type subunit 2B) codes for N-methyl d-aspartate receptor subtype 2B (GluN2B). It belongs to the N-methyl-D-aspartate receptor (NMDAR) gene family. It is located on chromosome 12p13.1. | | Biochem/physiol Actions | GRIN2B (glutamate ionotropic receptor NMDA type subunit 2B) plays an important role in the growth of neurons and is highly essential for learning and memory. GRIN2B mutation is associated with neuropsychiatric and developmental disorders like schizophrenia, Parkinson′s disease and bipolar disorder. MPEP (2-methyl-6-(phenylethynyl)pyridinehydrochloride) is used to treat Alzheimer′s disease (AD). | | in vitro | in recombinant expressed cells human mglu5a receptor, mpep inhibited quisqualate-stimulated phosphoinositide hydrolysis completely with an ic50 value of 36 nm whereas with no agonist or antagonist activities at cells expressing the human mglu1b receptor. mpep did not show agonist or antagonist activity on human mglu2, -3, -4a, -7b, and -8a receptors [1]. | | in vivo | in rat neonatal brain slices, mpep inhibited dhpg-stimulated phosphoinositide hydrolysis with a potency and selectivity similar to that observed on human mglu receptors. moreover, in extracellular recordings in the hippocampus ca1 area of anesthetized rats, the microiontophoretic application of dhpg induced neuronal firing that was blocked when mpep was administered [1]. | | IC 50 | 36 nm | | storage | +4°C (desiccate) | | References | [1] FABRIZIO GASPARINI . 2-Methyl-6-(phenylethynyl)-pyridine (MPEP), a potent, selective and systemically active mGlu5 receptor antagonist[J].
